Signals in 1 1/2 breaker arrangement

If the busbar is divided by bus-section disconnectors, the condition for the busbar
disconnector bay no other disconnector connected to the bus-section must be made
by a project-specific logic.
The same type of module (A1A2_DC) is used for different busbars, that is, for both
bus-section disconnector A1A2_DC and B1B2_DC. But for B1B2_DC,
corresponding signals from busbar B are used.
